摘要
核安全法规要求控制严重事故下核电厂安全壳内的氢气风险。在福清核电5、6号机组的设计中,针对严重事故后氢气风险的预防和缓解采取了多项措施,包括非能动氢气复合器、预防氢气局部积聚的工程改进等。采用一体化严重事故分析程序对上述措施有效性进行了计算论证,结果表明,福清核电5、6号机组的氢气风险控制措施能够有效应对威胁安全壳完整性的氢气风险,满足相关法规要求。
The hydrogen risk is required to be controlled according to nuclear safety laws and regulations.In the design of Fuqing No.5 and No.6 units,full consideration has been given to the prevention and mitigation of hydrogen risk,including hydrogen recombiner system,and engineering optimization to prevent local hydrogen accumulation.An integrated severe accident analysis code is adopted to demonstrate the effectiveness of the above measures.The results show that the hydrogen risk control measures of Fuqing No.5 and No.6 units can effectively deal with the hydrogen risk that threatens the integrity of the containment after serious accidents,which meets the requirements of relevant laws and regulations.
